You don't need to change the red pointer. On the contrary, you need to leave the red pointer where it was. The point is to let water into the system. The red pointer is there to tell you how much.

Find that tap - yours will be similar - and turn it anti-clockwise, while you watch the dial. The black needle should start moving up. When it's level with the red one, or just a tad below, turn the tap off. (Do this carefully...the pressure can change quickly.) Then use the reset button, as per irw's diagram above, and if you're lucky, you might be in business.

 

[swee'pea99]

You need to let more water into the system until your black needle is pointing to, roughly, one and a bit. Like this one.

 

[cyberknight]

That's worrying.

The top up water is going somewhere, probably escaping through a leak in a concealed pipe.

Might not be too bad if it's under the ground floor, but if it's upstairs it could lead to a large repair/decorating bill.

only goes down if you run the hot water , its like whatever is supposed to refill it isnt working

Friend is here now,bleeding the radiators for me.

That is NOT going to help, please read @swee'pea99's advice, you have NO pressure in the system, bleeding the radiators is only going to make it worse.

You NEED to pressurise the system, FIND the filling loop & gentle put 1-1.2 bar pressure in there.

Err, everyone (@Phaeton , @swee'pea99 , and anyone else) who is saying there is no pressure in the system should be aware that the only photo Accy had posted of the gauge was when he had the power off... @Accy cyclist , can you confirm if the BLACK needle on the gauge is at 0 when the power is ON?

Err, it will make no difference if power is on/off, it is a mechanical pressure gauge or at least every other boiler I have ever seen has a mechanical one

 

[ColinJ]

Yes, it should be (say) 1.0 - 1.5 bar when the system is not running and it will go up a bit to (say) 1.5 - 2.0 when the boiler is running.

 

[fossyant]

Should be around 1 - even with power off. Our van boiler is a similar model/age. It won't fire without the pressure being near 1 in the system. Bleeding rads won't help.

Apologies, just tried it with mine, you are indeed correct- for some reason I thought mine dropped to 0 when the power was off!

If I'm following the thread properly it seems like the boiler is losing pressure - contact the HA and get them to send an engineer they may replace the boiler as old and fit a new energy efficient one - refilling the loop like you did before will temporarily give you heat and hot water but it won't fix the problem, it will keep losing pressure and failing.

Bleeding the radiators won't cause any problems, but it will make the tops of your radiators warm again.

Apparently not

refilling the loop like you did before will temporarily give you heat and hot water but it won't fix the problem

He hasn't refilled the boiler/system, he has been advised multiple times, be he hasn't/won't/doesn't want to

Bleeding the radiators won't cause any problems, but it will make the tops of your radiators warm again.

If he already has zero/low pressure then letting even more water out will introduce air into the system, which is not what you want.

Yes,when the power's on the black needle is still on 0.

You need to fill it.

Take the woodwork off below the boiler. It's dead easy. Connect filler, turn on tap slowly, if it doesn't fill, turn off tap, undo grub screw slowly. Then turn on tap.

When at 1, turn off tap, turn off grub screw.
